Migrate ADC to new 5.x driver

[vroland]

Since IDF 4.x support is dropped, we can migrate to the new ADC driver.
This was extracted from #463 by @Bwooce.

@martinberlin If you have the time and a V5 board handy, could you test this change?

Looking good. This is my Serial output testing with dragon in a 6" board:

The dragon example doesn't actually read from ADC, afaik. Can you try again with the demo example?

[martinberlin]

I can but I'm afraid that is a V6 board not a V5. Actually after my move to Barcelona I don't really know where is my v5 board :(

[vroland]

Ok, then I can test in May when I'm back home.
